The frame of the machine co 1 provided-with corner posts '2' ally shown in Fig. 1, the carriage travelin from side to side of the machine in the usu -mannery 2A segment 5 has radially dis osed hangerssecured thereto by screws 7. ach hanger has a driver 8 pivoted thereto at 9 secured by a nut 23 bentito forr'n-a crank I ck ar' .t

The guide links of the system of type bars are ivot wire 14, each uide link eing receive and guided in a radial slot 15 in asegment 16. A pull link 17 is connected at its'rear end 18 to the associate driver 8, the forward end of the link being connected at-19 to a bell crank sub-lever 20. The sublevers are each pivoted at 21 to a hanger 22 to a segment 24. forwardly projecting arm of each bell crank sub-lever is connected to the upper end of a pivoted on a -link 25, the lower end of which is connected at 26 to an associate key lever 27. The key levers 27 are all pivoted on a pivot rod 28 secured to depending arms 29 which form art of a frame compris ng the segments 5 an 24. Each key lever is provided with a finger key 30 and an u ward y projecting armor member 31 whic latter is received in a slot 32 formedin a guide or comb, plate 33. The

comb plate forms part of an angular plate 34 secured by screws 35 to brackets 36. Brackets 37 are secured by screws 38 to the angular -.plate'3.4 near eachiside of the machinefiandare' provided with bearings 39 for the recep- The .tion of a rock. shaft 10. This rock shaft 40 is grooved throughout its length for the reception of a lockin bar or plate 41'which extends substantia lythroughout the length of. the bar and throughout the width of the keyboard of the machine, as shown in Fig. 4.

The right-hand end of the rock shaft 40' is arm 42 provided with a finger piece 43 by which the rock shaft may i be turned inits bearingsto move the locking bar to and from operative position, thgringp erative" position of the locking bar being shown in Fi 1 and the operative position of the locking ar being shown in Fig.2. The apertured near the right-hand screws 47 to theiunder side of the angular paws i. The'construbtion. 'is'such that" the the leaf spring is e'irerted against position when it is turned to such position throu h an actuation of the finger piece as in icated in Fig. 3. This same spring likewise bears against the upper wall'of the slot when the finger piece 43 is turned to the position shown in Fig. 2 to maintain the looking bar against accidental displacement in the operative position. time exerts a pressure towards t 1e axis of the rock shaft, thus tending to prevent the locking bar from, turning from the operative position. The shoulders 46 on the s ring 46 .abut the locking plate 41 at each .sie of the aperture 44 therein and limits the forward movement of the plate. The types '48 normallybear against the'inkin pad 49 contained in a case 50 which may e' detachably secured to the frame of the machine.- inking ad may likewise be detachably mounted in its trough-like case 50. One inking pad may be removed and another substituted therefor at will, either by removing the inking ad from its case or by lifting the case and t e inking :p'ad together out of the machine and substituting a new inking pad for the one which is exhausted. In orer to facilitate the removal of the inking pad it is desirable or necessary to remove all by the dotted of the types 48 from contact with the-inkin ad. It is for this purpose that the so-calle ocking bar 41 is provided. When-the locking bar is in the inoperative position shown in Fig.- 1 the types normally rest on'the ink pad and are free tobe actuated and to be moved to the rinting position as indicated fine in F1g.-1 at each depression of a key 30. When. it'is desired to remove: the inkin pad the finger piece 43 is moved rearwar ly from the position shown in Fig. 1 t0 that indicated in'Fig. 2. The effect of this movement is to turn the locking bar around an axis substantially coincident with one edge thereof and to simultaneously depress all of the key levers to the ositions shown in Fig. '2, thereby moving al of the jointed type bars sufiiciently to carry the types out of contact with the inkingpad as shown in Fig. 2 to facilitate a removal of the ad. When a new or re-inked pad has been introduced into the machine the fin er piece 43 is again moved to the osition s own in Fig; 1, thereby releasing al of the key levers and enabling the types to again contact with the inkin pad.
